@ur present invention relates to photog raphy and more particularly tothe treatment of exposed photographic prints in a liquid bath whetherdeveloping, washing, or fixing. The invention is particularly applicableto so-called automatic or semi-automatic cameras used in commercialphotography to make reproductions of various small objects,

particularly, documents and the like, which are photographed anddeveloped in one apparatus and delivered in a finished or semi--finished condition.

I The invention has for its object to provide an improved simple,

convenient, economical and efiicient machine of this characterespecially where prints are to be made upon paper or similar flexiblefilm sheets. The improvements are directed in part to the means formechanically car rying the exposed print to .the point of liquidtreatment and depositing it therein, and especially to means whereby theprint issubmerged in and uniformally and effectively given over totreatment by the liquid.

To these and other ends the invention resides in certain improvementsand combinations of parts, all as will be hereinafter more fullydescribed, the novel features being pointed out in the claims at the endof this specification.

Similar reference numerals throughout the several views indicate thesame parts.

We will first give a general description of the aims and operation ofour invention as shown in the accompanying illustrative embodiment:

The camera or exposing apparatus is of a well ,known or usual type. Asection of a continuous roll of sensitized paper is fed into into thefocal plane; exposed; fed out and severedinto a single sheet or print.An endless carrier provided with pin bars impales the advanced edge ofthe sheet and thereby carries it over a liquid treating receptacle.

After dragging the prints over the liquid in the receptacle, it stopsand the attached end of the print is immediately engaged by a strippingdevice which doffs it from the pin bar and causes it to fall flat intothe liquid.

The liquid bath receptacle has the form of a relatively shallow tray andconstantly reciprocates back and forth'so that a succession of waves areproduced that run from that have preceded it. Driving means is providedfor intermittently driving the carrier,

and for continuously operating the stripper and the liquid container. Inthe present instance this container serves as the final fixing bathafter the print hasbeen carried succes sively through a'developing bathand a washing bath, but the nature of the bath is immaterial to thisinvention except in certain particulars. I

Referring first more particularly to Figs;

1 and 3, 1 indicates generally a camera stand rovided with a verticallyadjustable copy board 2 at the front. Above this copy board is the usuallens and prism 3 on a fixed front 4 connected by bellows 5 with thecamera body 6, which is movable on the frame as usual for-focusingpurposes. The camera is fixed to a depending liquid treating ordeveloping apparatus 7 which moves with it. The magazine or paper rollis indicated at 8, the focal plane into which it is drawn in sections isindicated at 9, and the feed rolls at 10. Below the latter is the knifeor severing device 11 which severs the exposed print, and allows it todrop into a vertical chute 12. The lower edge of the print projects'fromthe open lower end 13 of this chute in a manner not necessary todescribe, but such as to permit it to be impaled upon and carried by anendless chain carrier 14. i

This carrier comprises two chains, one at each side of the machine, eachof which runs over a series of sprockets and rolls 15 and 16-'17. Thelatter two are given individual reference numerals for purposes of laterdescription in detail. The chains are connected at intervals by pin bars18 having pins 19 thereon (see Fig. 6) It is these pin bars thatdirectly engage and carry the prints. The driving of the carrier aslater described is such that aftera pin bar has picked u a print P, itcarries it into a developing tank 20 and comes to rest at the station Awhile the print is being treated therein. It then moves into a washingtank 21 and comes to rest at the station B while the print it carries isbeing treat-' ed therein, these two tanks being in the lower portion ofthe apparatus. The pin bar thence travels upwardly and forwardly over ahorizontal preferably shallow hypo or fixing tray or receptacle 22through which it drags or trails the print comin to a momentary restabove the forward end of the tray at a final station C. The particularmachine disclosed is a three pin-bar machine and it will be understoodthat the operation is continuous,

and while one bar and print is at one station with its print, the otherswill be at other stations with their prints.

It will be seen from following the path of the conveyer in Fig. 3 thatas the print journeys forwardly over the final fixing tray 22, itsemulsion or picture side is up, and its front.

edge lies on top of the pin bar and is partially turned downwardly overthe front of the latter on the impaling pins, which of course projectforwardly, and are then at the front of the bar. At station C the barloops upwardly and rearwardly around sprocket 17. It thus momentarilyreverses in direction and the pins 19 are then projecting rearwardlywith the print trailing from the under side except where its marginprojects its free edge upon and above the pins. The action is such thatat this point C the pin bar is wiped over in'a rearward direction by aswinging pendant stripper arm 23 vibrating forwardly and rearwardly on arock shaft 24. The stripper is provided on its lower endwith a pluralityof rubber or similarly yielding fingers 25 (Fig. 5) spaced apart forfree flexibility and to escape the pins 19 butto engage the edge of theprint and quickly detach it so that it falls fiat into'thepan 22. Thepin bar thence again reverses itself over-companion sprocket 16 andresumes its travel forwardly and downwardly to the pick up point 13.

The stripper23 vibrates back and forth continuously through meanshereinafter described in detail, so that it will always catch the pinbar during its periodic rest at station C. The front edge of the printwhen momentarily reversed with the pin bar at this point as described,has a tendency, naturally, to double over upon itself at times insteadof falling flat into the pan. To counteract this tendency we provide ata point between the reversing sprockets 16 and 17, a guide bar 26 thatresists the curling over of the print extending as it does above andacross it and the pan 22. We additionally provide a similar transversesto bar 27, similar to the bar 26 andarrangeda oveitinthe path of thestripper fingers 25. This last mentioned bar per limits the rearwardkick which the latter gives it, and halts it (the print) as soon as it.

has left the pins but without allowing further progress in a folding orlapping direction.

As before mentioned the tray or receptacle 22 that receives the printhas a constant reciprocatory movement forwardly and rearwardly in orderto produce waves in the liquid that will flow over, submerge, andthoroughly treat it. For this purpose it rests upon a pair of free rolls28 operating in cages 29 on an upper platform 30 in the developingcasing 7, or the rolls may have journals as shown at 31 in Fig. 9turning in fixed bearings 32. In either case a gentle endwisereciprocating movement'of the tray is effected with the result thatcontinuous waves of the form indicated in dotted lines in Figs. 10 and11 at 33 are produced which flow over and under the print indicated at Pin these figures. In this connection it is to be again noted that Fig.10 illustrates the beginning of the operative stroke of the stripper 23and has been dofied.

eavens It should be noted in Fig. 3 that the drip pan is closed on foursides so that any hypo that may splash out of the tray 493 will not fallinto the developing tanh or the approaches thereto, but that a hole 36is provided toward the rear of the drip pan through, which the draincoch 22projects which furnishes an outlet for liquid that ac cumulatesin the pan, and permits it to drain nto the water tank 21 where it maybe drained off into the sewer if desired.

ln print treating machines of this character. it is essential that noneof the fixing solution is carried into the developing solution, and thepeculiar arrangement of parts are designed so that the'print is carriedpositively through and totally submerged in the developing solution bythe carrier, but the carrier or any part thereof that reenters thedeveloping tank does not come in contact with the fixing solution. Thusthe front edge of the drip pan 30a the bottom of which constitutes theplatform 30 is sealed by a 2 bar 30?) on an upwardly and rearwardlyinclined baffle plate 300 (Fig. 3). 1

The tray is shown to have substantially square or vertical end walls 34in Figs. 7, 8, and 9, and curved end walls 35 in the'other figures. Weprefer the first mentioned contruction. In either case, we supply thetop of the end walls with overhanging ledges 86 which prevent the liquidfrom slopping over, and also help to produce a more effective wave. Thefront ledge is preferably provided with spaced fins 37 which reduce thetendency of the front edge of the wet print to adhere thereto in theevent that it falls thereon ashereinafter more fully explained.

The mechanism for operating the several agencies or mechanisms describedpreferably embodies a unitary drive with. transmission mechanism thatactuates the various parts in a synchronized or timed relationshlp. To

this end, referring particularly to Figs. 4, 7, 10 and 11 we provide amotor 38 mounted on a bracket 39 on a gear case 40 secured to the leftside of the machine. Arranged in alinement vertically in the gear caseis a driven sleeve 41 and a drive shaft 40 connected by Worm gear 42 tothe motor shaft 48. The driven sleeve shaft 41 through worm gearingindicated generally at 4 1 is arranged to turn a power shaft 45 carryinga pair of the sprockets 15 and whichgive motion to the chain conveyor.When a hand lever 46 on the right side of the machine (Fig. 1) is de-,pressed, it causes a dog 47 (Fig.4) on the same shaft 48 and on theopposite side of the machine to depress a plunger 49 which ear-v ries ashipper 50 that actuates a clutch element 51 on the drive shaft 40 intoengagement with the complementary clutch element 52 on the driven sleeveshaft 41, and thus the carrier 14 is set in motion through shaft 45.This driving of the carrier is for a short pe- 1. a tun ng thisinvention, but is disclosed in Landroclr Patent No. 1,780,489, grantedNovember 4, 1939.

Referring to Figs. 4, 10, and 11, the drive shaft 40 turns continuouslywith the motor shaft and through a worm 53 on its upper end in anannexed gear box 5 1 drives a spiral gear 55 provided with a crank pin56and a pitman 57. The other end of the pitman is pivoted at 58 to a bellcrank arm 59, the other arm 60 of which is connected by a link 61 with acrank 62 on the rock shaft 24 of the stripper 23. It is in this way thatthe stripper receives its continuous swinging.

wiping motion. At the same time arms 64 at each end of the shaft 65 thatcarries the bell crank 59-60 are similarly vibratin They are connectedby links 66 with cran arms 67 on one of the tray supporting rolls 528 sothat the movements of the pan in its reciprocatory action aresynchronized with those of the stripper as before stated. It is hereimportant to say that in this synchronized movement it has been foundbest to cause tbe'stripper 23 to move rearwardly or operativelyindisengaging the print while the tray or fluid receptacle is alsomoving rearwardly' or in the same direction, the reason being that thefrictional contact of the liquid with the print assists the stripper toa slight degree in pulling the print off the impaling pins, and istraveling away from the forward end of the print instead of toward andunder it, whereby the folding over of the print thatis to be avoided iscombated. If the tray moved forwardly while the stripper was strippingin a rearward direction the tendency would be to throw the body of theprint under the partially curled end of the print at the moment of itsdisengagement.

In furtherance of this idea of aiding the stripper 23 in every way tonot only disengage the printfrom the impaling pins 19 but to cause it tofall quickly and in a flat condition within the liquid in the receptacle22 we prefer to provide the latter at the top of its rear wall with anoverhanging ledge 68 that performs the same function at that end as theledge 36 at the forward end in producing a suitable agitating wavewithout spilling the liquid. This ledge 68 is,of substantial width andhas asmooth flat continuous surface. As the tail end of the wet print istrailed over it, it has a tendency to adhere thereto and offers suchresistance or retarding action particularly. in connection with themovements of the receptacle itself as will cause it to prevent the printfrom overriding, hold it with a degree sists of a plurality of spacedfins 37, the thin edges of which present themselves as the contactingsurface.

Inasmuch as the receptacle '22 preferably lies loosely on the rolls 28so that it maybe readily removed and replaced in the accustomed mannerof a stationary tray, wepreter to provide butters or stops on theplatform 30, so that it, through the inertia of its reciprocatorymovement, it creeps or slides upon the rolls, it will-be limited by thebutter stops and straightened out again.

In Figs. 7 and 8, I have shown a modified and somewhat simpler manner ofconnecting up the stripper and tray oscillating rolls with thetransmission mechanism of the motor; A crank arm 71 is'secured to thegear 55 and is connected by a link 7 2 with a bell crank arm 73 turningon a transverse shaft 74 extending beneath the receptacle 22, allincased in an extension housing 75. The other arm of the bell crank 76is on the inside of the casing 7 between the side wall thereof and thereceptacle and is pivoted at 77 to a crooked link 78 which isdirectly'pivoted at 79 to an arm 80 on the rock shaft 24 of the wiper.said arm corresponding to the arm 61 shown in the other view and theaction being substantially the same. In these views also a differ- ,entform of actuating dog 81 is used to depress the plunger or push rod 49,but its action is the same and it turns with the operating shaft 48 asbefore.
